Description

Technical Field

[0001] The utility model relates to the field of homogenizers, in particular to a high-pressure jet homogenizer used for emulsion production. Background Art

[0002] Emulsion is an important liquid preparation, widely used in food, cosmetics, medicine and other industries. The quality of emulsion depends largely on its uniformity and stability. Traditional homogenization methods such as high-speed stirring and high-pressure homogenization can improve the uniformity of emulsion to a certain extent. High-pressure jet homogenization technology is a new homogenization method developed in recent years. Its basic principle is to use a high-pressure pump to pressurize the emulsion to tens of MPa, and then spray it at high speed through a special homogenization valve, and use extremely high shear stress to break the droplets in the emulsion, so as to obtain an emulsion with smaller particle size and more uniform distribution. Compared with traditional homogenization methods, high-pressure jet homogenization has the advantages of high efficiency and low energy consumption, and shows broad application prospects in the industrial production of emulsions.

[0003] The homogenizing valves of existing equipment usually adopt a simple structure of a conical valve core and a valve seat. When the emulsion passes through the annular gap under high pressure, the shear stress is unevenly distributed and the shear strength in some areas is insufficient, resulting in poor homogenization effect and difficulty in meeting the production requirements of high-quality emulsions.

[0037] The following is combined with Figure 1-7 To further explain this application in detail,

[0038] Emulsion is an important liquid preparation, which is widely used in food, cosmetics, medicine and other industries. The quality of emulsion depends largely on its uniformity and stability.

[0039] The homogenizing valves of existing equipment usually adopt a simple structure of a conical valve core and a valve seat. When the emulsion passes through the annular gap under high pressure, the shear stress is unevenly distributed and the shear strength in some areas is insufficient, resulting in poor homogenization effect and difficulty in meeting the production requirements of high-quality emulsions.

[0040] In order to solve the above problems, the embodiment of the present application discloses a high-pressure jet homogenization device for emulsion production, comprising a support frame 1 and a shell 2, wherein the shell 2 is fixedly connected to the outside of the support frame 1 and is used to protect the components inside the support frame 1, and an observation window 21 and an operation door 22 are provided on the shell 2 for observing and maintaining the components inside the support frame 1. ;

[0041] A supporting plate 3 is fixedly mounted on the supporting frame 1 , and a high-pressure pump assembly and a homogenizing head assembly 9 are fixedly mounted on the supporting plate 3 . The high-pressure pump assembly is used to pressurize the emulsion to be homogenized and transport it to the homogenizing head assembly 9 for homogenization.

[0042] The high-pressure pump assembly includes a driving mechanism 4 and a limit assembly; the driving mechanism 4 includes a driving motor 41, a first belt pulley 42, a belt 43 and a driving wheel set;

[0043] The output shaft of the driving motor 41 is coaxially fixedly connected to the first belt pulley 42 , and the first belt pulley 42 is drivingly connected to the driving wheel set via a belt 43 .

[0044] The driving wheel group includes a rotating shaft 44, an eccentric wheel 45, a driving sleeve 46 and a traction rod 47;

[0045] The rotating shaft 44 is fixedly mounted on the support frame 1 through a bearing seat, the eccentric wheel 45 is fixedly mounted on the rotating shaft 44, the driving sleeve 46 is rotatably mounted on the outside of the eccentric wheel 45, one end of the traction rod 47 is hingedly connected to the driving sleeve 46, and a second belt pulley 48 is coaxially mounted on one end of the rotating shaft 44, and the second belt pulley 48 is connected to the first belt pulley 42 through a belt 43.

[0046] The limiting assembly includes a limiting sleeve 5 and a connecting rod 6; the limiting sleeve 5 is fixedly mounted on the support frame 1, and the connecting rod 6 is slidably inserted in the limiting sleeve 5. One end of the connecting rod 6 is hinged to the other end of the traction rod 47, and the other end is fixedly connected to a plunger 8 through a threaded connector 7. The limiting sleeve 5 is used to limit the movement direction of the connecting rod 6 to ensure the reciprocating motion of the connecting rod 6.

[0047] A liquid supply seat 82 is disposed on the outer side of the plunger 8, a liquid supply channel 83 is provided on the liquid supply seat 82, and a liquid supply port 81 connected to the liquid supply channel 83 is provided on the liquid supply seat 82, and the emulsion to be homogenized enters the liquid supply channel 83 through the liquid supply port 81;

[0048] The connecting rod 6 drives the plunger 8 to reciprocate, pressurizes the emulsion and delivers it to the homogenizing head assembly 9.

[0049] Specifically, the driving motor 41 drives the driving wheel set (rotating shaft 44 , eccentric wheel 45 , driving sleeve 46 ) to rotate through the first belt pulley 42 and the belt 43 .

[0050] The eccentric motion of the eccentric wheel 45 drives the connecting rod 6 to perform reciprocating motion through the driving sleeve 46 and the traction rod 47. The connecting rod 6 can only perform axial reciprocating motion under the constraint of the limiting sleeve 5.

[0051] The connecting rod 6 drives the plunger 8 fixedly connected at its end to do reciprocating motion. The plunger 8 reciprocates in the liquid supply channel 83 in the liquid supply seat 82 to pressurize the emulsion entering the liquid supply port 81.

[0052] The pressurized emulsion is transported to the homogenizing head assembly 9, where the emulsion is fully homogenized and demulsified, thereby obtaining a high-quality emulsion product.

[0053] The eccentric wheel 45 is used to drive the plunger 8 to reciprocate, the structure is simple and compact, the transmission is stable and reliable, the noise is low, and the maintenance is convenient.

[0054] The limiting sleeve 46 effectively constrains the movement direction of the connecting rod 6 and the plunger 8, ensuring their stable reciprocating motion, reducing the lateral load and extending the service life.

[0055] The closed housing 2 effectively blocks noise and prevents damage caused by splashing of the emulsion, and is suitable for application in the fields of food, medicine, etc.

[0056] The use of high-pressure jet homogenization overcomes the problem of uneven shear strength distribution of traditional homogenizing valves and can significantly improve the homogenization quality of the emulsion.

[0057] The homogenizing head assembly 9 is integrally connected to one side of the liquid supply seat 82;

[0058] The homogenizing head assembly 9 includes a homogenizing valve seat 91, a liquid inlet 92, a homogenizing valve core 93, a valve stem 94, an impact ring 95 and a liquid outlet 96;

[0059] The liquid inlet 92 is provided on the homogenizing valve seat 91 and communicates with the outlet of the liquid supply channel 83;

[0060] The homogenizing valve core 93 is slidably installed in the homogenizing valve seat 91, one end of the valve stem 94 is fixedly connected to the homogenizing valve core 93, and the other end extends to the outside of the homogenizing valve seat 91 for adjusting the position of the homogenizing valve core 93;

[0061] The impact ring 95 is fixedly installed in the homogenizing valve seat 91 and is located opposite to the homogenizing valve core 93;

[0062] The liquid outlet 96 is provided on the homogenizing valve seat 91 for outputting the emulsion after homogenization.

[0063] The impact ring 95 includes a multi-channel ring body 951 and a plurality of impact protrusions 952. The ring body 951 is fixedly connected to the inner wall of the homogenizing valve seat 91. The impact protrusions 952 are evenly distributed on the ring body 951 along the circumferential direction and extend toward the homogenizing valve core 93.

[0064] The cross section of the impact protrusion 952 is triangular, and an annular gap is formed between the top of the impact protrusion 952 and the end surface of the homogenizing valve core 93 for high-speed passage of the emulsion to shear and homogenize the emulsion.

[0065] Specifically, the emulsion pressurized by the high-pressure pump assembly enters the liquid inlet 92 on the homogenizing valve seat 91 through the liquid supply channel 83 .

[0066] The emulsion flows in the homogenizing valve seat 91 and passes through the annular gap formed between the homogenizing valve core 93 and the impact ring 95. The axial position of the homogenizing valve core 93 can be changed by adjusting the valve stem 94, thereby adjusting the width of the annular gap and controlling the shear strength and flow rate of the emulsion when passing through.

[0067] The impact protrusions 952 evenly distributed along the circumferential direction on the impact ring 95 and the end surface of the homogenizing valve core 93 form a plurality of triangular flow channels. When the emulsion passes through the narrow flow channel under high pressure, the speed is extremely high and it is subjected to strong shear force. At the same time, the high-speed jets of the emulsion in the adjacent flow channels collide violently inside the impact ring 95, generating strong shear and turbulence, so that the emulsion is fully homogenized and demulsified.

[0068] The homogenized emulsion is discharged from the liquid outlet 96 and enters the subsequent process or packaging link.

[0069] The impact ring 95 structure is adopted, and the evenly distributed triangular impact protrusions 952 on the ring body and the end face of the homogenizing valve core 93 form multiple high-speed jet channels. The emulsion is subjected to strong and uniform shearing when passing through, which significantly improves the homogenization quality of the emulsion and overcomes the problem of uneven shear strength distribution of the traditional conical valve core homogenizing valve.

[0070] By adjusting the position of the homogenizing valve core 93 through the valve stem 84, the width of the annular gap can be flexibly controlled, the shear strength and flow rate of the emulsion can be adjusted, and emulsion products with different viscosities and components can be adapted to improve the application range of the equipment.

[0071] The working steps of the high-pressure jet homogenization device are as follows:

[0072] 1. Emulsion supply and pretreatment:

[0073] The emulsion to be homogenized enters the liquid supply channel 83 on the liquid supply seat 82 through the liquid supply port 81 .

[0074] The driving motor 41 is started to drive the driving wheel set (including the rotating shaft 44, the eccentric wheel 45, the driving sleeve 46 and the traction rod 47) to rotate through the first belt pulley 42 and the belt 43.

[0075] 2. Emulsion pressurized delivery:

[0076] The eccentric wheel 45 rotates with the rotating shaft 44, driving the outer driving sleeve 46 to perform circular motion.

[0077] The driving sleeve 46 drives the connecting rod 6 to perform axial reciprocating motion in the limiting sleeve 5 through the traction rod 47. The movement direction of the connecting rod 6 is constrained by the limiting sleeve 5 to ensure stable reciprocating motion.

[0078] The connecting rod 6 drives the plunger 8 threadedly connected at its end to reciprocate in the liquid supply channel 83. The reciprocating motion of the plunger 8 pressurizes the emulsion, and the pressurized emulsion is transported to the homogenizing head assembly 9.

[0079] 3. Emulsion homogenization treatment:

[0080] The pressurized emulsion enters the liquid inlet 92 on the homogenizing valve seat 91 through the liquid supply channel 83 .

[0081] The emulsion flows in the homogenizing valve seat 91 and passes through the annular gap formed between the homogenizing valve core 93 and the impact ring 95. By adjusting the valve stem 94 to change the axial position of the homogenizing valve core 93 and adjust the width of the annular gap, the shear strength and flow rate of the emulsion passing through are controlled.

[0082] The emulsion is subjected to strong shearing under high pressure when passing through the narrow flow channel formed by the evenly distributed triangular impact protrusions 952 on the impact ring 95 and the end surface of the valve core 93. The high-speed jets of adjacent flow channels collide violently inside the impact ring 95, generating strong shearing and turbulence, making the emulsion fully homogenized and demulsified.

[0083] 4. Homogeneous emulsion output:

[0084] The emulsion after homogenization is discharged from the liquid outlet 96 of the homogenization valve seat 91, and the homogenized emulsion enters the subsequent process or packaging link.

[0085] 5. Equipment maintenance and adjustment:

[0086] The operating status of the equipment can be observed through the observation window 21 on the shell 2, and maintenance can be carried out through the operation door 22. According to the properties of the emulsion, the position of the homogenizing valve core 93 can be changed by adjusting the valve stem 94 to adjust the homogenizing effect. The equipment can be cleaned and maintained regularly to ensure long-term stable operation.

[0087] The equipment has a reasonable structure and clear working principle. The emulsion supply, pressurization, homogenization, and output parts are connected in sequence, and the process is smooth. The impact ring homogenization structure is adopted to significantly improve the homogenization quality of the emulsion.
